Hi, All,
    I am now learning the mechanism Cassandra adopts to get high availability and fault tolerance.  As I know, we should connect to one server of Cassandra first, then we can read or write data  through it, so if the server which we connect to get down, what will happen? Should we have to reconnect another server or will Cassandra control this situation? Another sutiation, if the server which is involved in the process of data reading fail, what will Cassandra do?
    Thanks a lot!
